My 22S came with a front Hi-Viz sight. It's fine, except that it has a rounded top. There is no way to accurately/quickly line it up with the flat-top rear sight wings. I don't shoot it much these days, so no big deal. If you line up dots, as in the three dot system, then the Hi-Viz dot would be great between two rear dots, but the rear leaf doesn't have dots. Go figure. A near miss by S&W.
